A substance is precipitated from the solution when two solutions containing soluble salts are combined.

• A reaction to precipitation is the formation of an insoluble salt on combining two solutions containing the soluble salts.
• The insoluble salt falling out of the solution the precipitate,.
• Precipitation reactions occur when aqueous solution mixes cations and anions to form an insoluble ionic base, called a precipitate.
• Whether or not such a reaction can occur can be calculated using the rules on solubility for rising ionic solids
